Help i'm being attacked by digital distortion

    OK first of all my set up is a tascam us-122 and my onboard sound card realtek 97 using the asio4all driver.... ok so I start recording or playback and after a few minutes (it varies) I start to get digital distortion, at which point I go to preferences change the driver to someting other then asio4all then back to asio4all (if that makes sense) and the distortion goes away for a few minutes.... also i've just noticed it doesn't effect the recording... just the playback
    how can i fix this

    What do you mean by "digital distortion"? What are you monitoring with? Do you get the same result on headphones as well as speakers? If you re-start the replay after a few minutes rest without re-initialising the driver do you get the same result, or does it distort immediately?

    If you have the tascam, why are you using the onboard sound card and asio4all? Use the tascam as your interface and use the asio driver that tascam provided for it. Think of the tascam as an external sound card, and stop using the POS realtek completely.

    I get this crackling, just using my headphones or speakers (from the realtek) and no it distorts immediatly

    theres way too much latency...

    If there's too much latency, you're doing something wrong. When you go into Cubase LE(I'm assuming here because that's what should have come with your Tascam), go to your device settings and choose TASCAM ASIO for your driver. NOT ASIO full duplex and NOT ASIO Mulitimedia. TASCAM ASIO(or US122 ASIO or whatever it appears as in Cubase). You should be able to reduce your latency to at least 10ms unless your computer is particularly slow.

    ASIO4ALL is a hack at best. The realtek card should be out of the picture completely.

    The "digital distortion" you are hearing is drop outs due to ASIO4ALL's inability to maintain sync between the Tascam and the Realtek.

    Yes indeed, the problem is the latency with the tascam. Solve that and get rid of the realtek and you will be happy for a long time. Search this forum for "latency", and even google it, you'll get about one bazillion answers about how to reduce it. For starters, make sure your hardware is compatible (tascam should provide a list of supported hardware for that particular interface on their website, I would hope). Good luck!
